  1. Johnson M, MacLean K, Caspers M, Prisinzano T, Griffiths R. Time course of pharmacokinetic and hormonal effects of inhaled high-dose salvinorin A in humans. J Psychopharmacol. 2016;30:323-9 pubmed publisher
    ..This is the first study to demonstrate a direct relationship between changes in plasma levels of salvinorin A and drug effects in humans. The results confirm the efficacy of an inhalation technique for salvinorin A. ..
  2. Sheffer C, MacKillop J, Fernandez A, Christensen D, Bickel W, Johnson M, et al. Initial examination of priming tasks to decrease delay discounting. Behav Processes. 2016;128:144-52 pubmed publisher
    ..These findings provide support for the development of a brief priming intervention that might be examined in clinical or public health contexts to decrease discounting and support healthy choices. ..
  3. Johnson M, Herrmann E, Sweeney M, LeComte R, Johnson P. Cocaine administration dose-dependently increases sexual desire and decreases condom use likelihood: The role of delay and probability discounting in connecting cocaine with HIV. Psychopharmacology (Berl). 2017;234:599-612 pubmed publisher
    ..Lack of monetary effects highlights the importance of studying clinically relevant outcomes when examining drug effects on behavioral processes. ..
  4. Johnson M, Griffiths R. Potential Therapeutic Effects of Psilocybin. Neurotherapeutics. 2017;14:734-740 pubmed publisher
    ..US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms. ..

    Johnson M, Bickel W, Baker F. Moderate drug use and delay discounting: a comparison of heavy, light, and never smokers. Exp Clin Psychopharmacol. 2007;15:187-94 pubmed
    ..These data suggest that even moderate levels of drug use may be associated with high delay discounting levels. ..
  6. Johnson M, MacLean K, REISSIG C, Prisinzano T, Griffiths R. Human psychopharmacology and dose-effects of salvinorin A, a kappa opioid agonist hallucinogen present in the plant Salvia divinorum. Drug Alcohol Depend. 2011;115:150-5 pubmed publisher
    ..Under these prepared and supportive conditions, salvinorin A occasioned a unique profile of subjective effects having similarities to classic hallucinogens, including mystical-type effects. ..
  7. Herrmann E, Johnson P, Bruner N, Vandrey R, Johnson M. Morning administration of oral methamphetamine dose-dependently disrupts nighttime sleep in recreational stimulant users. Drug Alcohol Depend. 2017;178:291-295 pubmed publisher
    ..Future research should examine relations between stimulant use and sleep disruption in naturalistic settings, with regard to both stimulant abuse and licit prescription use. ..
